Continuous sanitisation |
(57) A continuous sanitisation method particularly for the sanitisation of packs containing
sterile containers for sterile injectable material so as to prevent cross-contamination
by the packs of the containers during handling of the packs to remove the containers
therefrom requires sanitisation medium to be admitted to and then removed from a sanitisation
chamber comprised by a sanitisation tunnel for the overall handling of the packs in
which chamber a relationship between concentration of sanitisation medium in the sanitisation
chamber and time which posses a square wave form is maintained. Between each cycle
of sanitisation operations within a sanitisation chamber, rinsing with air takes place,
which air, when withdrawn, is subject to catalytic decomposition of vapour phase sanitisation
medium entrained therein.
